To al?, wtmn it may/concern:

Be it known that I,'IIERBERT H. JAGOBUS, a citizen of the United States, residing at Verona, in the countyof Essex` and. State of New,

Jersey, have invented certain new and useful Improvements in Printing-Machines, of which the following is a specication.`

This invention relates to improvements in printing-machines, and especiallyto a machine for printing and embossing a continuous web; and it has for its main object the provision of a machine of this type adapted Afor printing successive separatedportions of a web and for embossing those parts of the web between or intermediate of the printed portions of itssurface. Usually the invention will be embodied ina machinehaving two or more printing members or y cylinders suitably connected or` geared to make registering impressions on one side of the traveling web, these printing operations usually taking place successively and the web being embossed betweenthe printed portionafter the last printing operation has been finished. Although a machine of this general type is suitable for manydifferent kinds of printing, yet the one shown and described herein is especially designed and intendedk for printing and embossing one side of a traveling fabric or cloth of the species known to the trade as pyralim and a machine such as that illustrated herein, which is a suitable onefor the purpose of printing and embossing this kind of cloth, is' known as a picotographmachine.

The machine illustrated herein is not only intended to form a series of registering impressions upon the face of the traveling web and to emboss the surface between such impressions; but these registering impressions will ordinarily be printed in different colors, the first printing-cylinder printing upon the web in one color iigures ot' a design which are of one size,while the next impression member or printing-cylinder will imprint the surface of the cloth to produce gures of the design in another color, which figures will register with the ones first printed, but will usually surround and therefore be larger than such first figures.

In connection with the printing and embossing-mcans which I employ I also prefer toemake use of means for drying the ink or other "material used to' form the impressions, and one of these drying devices will ordinarily operate to dry the printed part of the web before the latter is acted upon by the embossing means. Another drying device may operate afterward to dry whatever ink or other material may chance to adhere to the face of the embossing-cylinder, and after it has been so dried this ink may be cleaned off in some suitable manner, as by a rotary brush.

For the purpose of inking the impression means'or printing-cylinders I prefer to employ an improved type of inking apparatus in which a more thorough and even distribution of the ink is obtained than in inking apparatuses as ordinarily constructed. The salient features of this improved inking apparatus will be fully set forth hereinafter.

Other novel features of the invention relate to themoun'ting and adjustment of the printing-cylinders so`that one of a pair of coperating printing-cylinders may be raised slightly from the other to permit inspection of the work and also removed bodily from the machine to permit the substitution of another cylinder having a different pattern; to improved impression cylinders, only one of which need in this case have dies on its embossing-Eace,while the other mayhave a yielding face preferably made up of a plurality of layers of tissue-paper, into which the male dies of the other embossing-cylinder may sink to form the female impressions or dies and properly emboss the traveling web,it being understood that the embossing-cylinder having the male dies or embossing members thereon may be mounted on and be removable from the m achine in substantially the manner just described with respect to the printing-cylinders to a novel retarding device for varying the pressure exerted'on the roll of webbing as the latter is unwound and the web is fed forward; to a novel frictional driving confoo certain other features of construction, all of which will be fully described hereinafter in detail. n

In the drawings accompanying and forming part of this specification and in which I have illustrated a printing machine especially adapted for the purpose of printing and embossing a continuous web of picot, Figure 1 is a side elevation of such machine. Fig. 2 is a substantially-central longitudinal section of the same. Fig. 3 is an enlarged side elevation of a portion of the machine, illustrating in detail one of the inking apparatuses and coacting devices, parts being broken in order to illustrate th e construction more clearly. Fig. 4 is a sectional plan of the same broken in the center. Fig. 5 is a front elevation of the same, also broken in ,the center'. Fig. 6 is an enlarged front elevation of a detail illustrating the mounting for one of the printingcylinders and the devices for adjusting it. Fig. 7 is an enlarged t-ransverse section of the ink-fountain and the inking-rollers, illustrating one position of the latter for feeding ink. Fig. 8 is a similar View illustrating another position of such rollers. Figs. 9 and 10 are enlarged sectional details illustratinga clutch connection for the ends of the cylinder-shafts for permitting the removal of a cylinder and the substitution of another, these views showing the open and closed posi tions of the clutch. Fig. 11 is a detail illustrating in end elevation my improved frictional driving connection for the rewinding-roll. Fig. 1'2 is a longitudinal section of the same. Fig. 13 is an enlarged detail of portions of the coacting surfaces of the embossing-cylinders,illustrating the manner in which the female die is formed in the yielding surface of one embossing-cylin der by the male dies of the other cylinder.

Similar characters of reference designate corresponding parts in the different figures of the drawings.

Any suit-able framework maybe employed for supporting the several operative parts of my improved printing-machine, that illustrated herein embodying two heavy side frames or castings, such asAA, suitably connected. At the left-hand end of the machine as seen in Fig. 1 the material to be printed and embossed will usually be carried in the form of a large roll, such as R, suitably supported for rotation, as by a shaft 2. This shaft may be mounted adjustably in a halfbearing, such as 3, open at the upper side and intersected by inclined ways, such as 4, at opposite sides of the framework. The initial ends of these inclined guideways are substantially of the same height from the iioor4 on whichA the machine is supported as the shaft 2 of the roll, and hence the shaft at its opposite ends may be brought against these inclined guides and the roll easily forced up the incline until the shaft 2 drops into the bearings 3.

Suitable web-feeding means will be .employed for advancing the contin nous web (indicated herein by w.) through the machine, and this web-feeding mechanism will generally be driven from the extreme opposite or right-hand endof the machine, at which I will ordinarily locate on a shaft, such as 5, which may be su pported in half-bearings similar to those just described and intersected by corresponding inclined guides 6, a rewinding-rollei-,such as r', on which the printed and embossed web may be rewound. In the construction illustrated this rewinding-roller is Adriven from the main shaft 10 of the machine by a train of gearing including the pinions and gears l0', 12', 13', 14', 15', 16', 17', and 18', the latter of which is carried by a shaft 18, on which is also mounted a driving band-wheel, such as 18", from which a crossed belt 2O runs to the outer member or ring 22 of the frictional driving device hereinbefore mentioned and which is indicated herein in a general Way byf. This ring will encircle in this case a plurality of shoes 23, having their working faces defined by arcs of the same circle, the body portions of these shoes being indicated herein by 23' and being preferabl y tubular members or arms disposed radially to the axis of the shaft 24, by which they are carried. These members may be supported in radial sockets 25' in a shoe-carrier, such as 25, fixed on the shaft 24. These radial arms 23' of the respective shoes will work snugly but freely in the sockets 25', and the shoes should be pressed outward normally by strong springs, such as coil-springs 26, in order to maintain the shoes in driving engagement with the ring 22, except when there is an abnormal pull upon the web, due to the increase in size of the roll R' as the printed and embossed web is rewound.

As the roll R is liable to be turned too rapidly unless some means is provided for checking its rotation, I prefer to employ a retarding device, such as that indicated in a general way by T, for exerting on the surface of the roll ot' webbing a constant pressure. As the web is unwound and the roll decreases in size this pressure should decrease, and hence the retarding device indicated herein is constructed to exert upon the roll R such a gradually-decreasing pressure. In this case I prefer to employ a retarding device embodying a counterweighted lever or lever-frame the upper arms of which, as 30, carry a roll 31, While to a lower arm is pivoted a link, such as 30", which in turn is pivoted to a weight 3Q"', carried by a lever 32', connected at its free end to a strap 32, passing around the shaft 2, carrying the roll R, this weight being shiftable along the lever 32', so as to exert a decreasing leverage as the web unwinds from the roll R, to thereby exert a decreasing pressure upon the roll of webbing through the roller 31. This retarding device may be suitably mounted, as on a rod or shaft 33, carried by the framework.

In connection with the retarding device just described I may also employ a tension IOO IIO

device for drawing the web out of a straight line as it is unwound, and for this purpose I have indicated at T a coun-terweighted frame in the supporting-arms 35, of which a guideroller, such as 35', may be loosely mounted for rotation, this guideroller preferably having at opposite ends thereof stop -flanges, such as 35", for positively positioning the web sidewise. This tension device or frame may be weighted, as indicated at 8G. As the web passes beyond the roll 35' it may be carried over a guide-roller, such as 37, preferably supported in half-bearings, such as 38, on the framework in order to be removable readily from the latter. After passing beyond the guide-roller 37 the web fw is Iirst carried between the impression members or cylinders of the first pair of printing members, after which it may be carried over a roll, such as 40, for dellecting the web from a straight line to an extent sufficient to assure proper registration of the printed figures or devices, the web being then passed between a second pair of printingcylinders and imprinted wit-h figures or devices which will register with those imprinted by the iirst pair of cylinders. The web will then be carried ordinarily over another adjustable roll 40', similar to that shown at 40 and operativein the same manner to deflect the web before it reaches the embossing-cylinders, and thus assure the presentation of the proper portions of the surface of the web to the action of the embossing members, the portions to be embossed usually being those located between the printed sections of the surface. Before reaching the embossing-cylinders, however, the web may be heated to dry the ink or print ing medium thereon, and after passing between the embossing-cylinders that embossing-cylinder which carries the male dies may be heated and cleaned to remove any ink which may adhere thereto, the web usually passing on then to the rewinding-roller fr', hereinbefore mentioned.

In the preferred construction not only are the adjustable rolls 40 and 40' substantially of the same type, but the rst and second pairs of printing-cylinders and their accessories, together with the inking devices coperative therewith, are substantially of the same construction, except, of course, as to the surfaces of the printing-cylinders, and hence a description of one pair of printing-cylinders and of one of the inking apparatuses will suffice for both of these similar mechanisms. The pinion l0' on the shaft 10 will in this case drive the impression cylinder 50 directly through the medium of a large spur-gear 5l, carried by a shaft 52, suitably journaled in the side frames A A, and the movement of l j the gear 5l will be transmitted to a gear 53 of the same size on one part of a rotary member c may be shifted toward or from each other to control the impression or inspect the work. In addition to this it is also desirable that the upper cylinder C, which in this case is the main one or printing-cylinder proper, should be capable of removal from the machine readily in order to permit the insertion of a cylinder with another pattern without disturbing the remainder of the mechanism. Hence I have illustrated herein means forpermitting removal of the cylinder C bodily from the bearings in which it is mounted, and preferably the same mountings will be employed at both ends of the central portion or shaft proper, 55,0f the rotary member which carries this cylinder, and therefore a description of one of such connections will also suffice for both. Here the end of the shaft 55 is squared at 5G (see Figs. G, 9, and l0) and is inserted between a pair of complementaryclutch members 57, having complementary sl1aftengaging jaws substantially of the same shape as the end 56 of the shaft, but spaced so as to leave a slight opening at 58 even when the clutch members are closed. Said clutch members are preferably mounted to slide in a guide or guideway, such as 59, disposed transversely to and at the inner end of a rotary member which forms part of the support for the cylinder O, this rotary member being designated by 60 and being journaled for rotation in a suitable bearing.

The two members 57'of the shaftclutch may be clamped together in any desired way when the cylinder is positioned and is to be rotated; but the clamping means I prefer to employ is a right and left hand screw or screw-bolt, such as 6l, which will shift the two clutchsections in opposite directions simultaneously to close them on the squared end 56 of the shaft 55 or else to loosen them from the shaft and free the latter. lVhen they are shifted away from each other to the positions shown in Fig. l0, it will be seen that the opening 58 will then be wider than the squared end of the shaft, and when the clutches at opposite ends of the shaft are thus operated it will be apparent that the cylinder may be raised from the machine and hoisted clear of the mechanism and another printing-cylinder afterward inserted in its place.

In order to provide for cndwise adjustment of the printing-cylinders, I prefer to make use of adjusting-screws, such as G5, which in this case are passed through the members 60, on which the cylinders are mounted, these adjusting-screws being disposed in alinement with the shaft 55 and engaging the outer ends of the squared portions 56 of said shafts. (See Fig. G.) The manner in which these screws will be manipulated to effect the desired adjustments will be apparent.

In order to provide for a slight adjustment of the printing-cylinder C toward or from the impression-cylinder c to regulate the impres sion or to inspect the work, I prefer to mount the rotary members G0 in ad j ust-able bearing- IOO IIO

boxes, such as 66, these latter being suitably supported in squared openings in the frame-4 work, (see Figs. 3 and 6,) these openings being sufficiently large to permit vertical adjustment of the bearing-boxes. Here the cylinder, the member on which it is mounted for rotation, and the bearing-boxes may be su pported on longitudinally-movable, but nonrotating, adjusting members or rods and located by adj ustin glscrews 67 ,passed throu gh the caps 68 of the boxes or bearings, the positions of these screws of course determining the height of the cylinder C. In order to in* dieate just what this position is, I prefer to employ in connection with the bearing-boxes and the adj usting-screws 67 therefor the stoprods 70, suitablysupported in the framework and positioned to engage the under sides of the bearing-boxes. It will be apparent that when the bearing-boxes 66 engage these stoprods 70 the cylinder should be in a true horizontal position, and these rods are preferably geared together to move in unison to indicate on a proper scale or 'dial the extent of the adjustment of the cylinder C in Vertical direction when it is moved from one position to another. Here the stop-rods at the lower ends thereof are screwed into worin-gears 7l, meshing with corresponding worms on a long wormshaft 73, suitably journaled in the side frames 'A A and carrying at one end thereof a handwheel 74, having thereon a scale 75 for indicating the adjustmentof the cylinder. An indicator, such as a pointer 76, should coperate with this scale. It will be apparent that if the cylinder C is in a properly-adj usted position to cooperate with the cylinder c and it is then raised toinspect the work the position of the scale should be noted before the adjustment is changed, and then afterinspecting the work the cylinder C may be readily restored to its original position by turning the l1and-wheel 74 until the division before noted on the scale is opposite the pointer 76, whereupon the cylinder may be lowered until the bearing-boxes rest on the posts 7 O.

It should be noted that each of the stoprods 70 will usually be splined in its bore and will be screw-threaded for at least a portion of its length in order that it may coperate With internal threads of the vertically-fixed worm-gear 7l and be held securely in any adjusted vertical position.

The second printing mechanism is Substantially similar in all respects to that just described, except that it is driven from the main shaft lO by the pinions 12 and 13 and a spur-gear 14 on the lower cylinder c of the second pair, the gear 14 meshing with a similar large gear 53' on the rotary supporting member which carries the cylinder C'. From the spur-gear ll movement is irnparted, by means of the gears 15', 16', and 17', to the large spur-gear 1S on the shaft 18, carrying the lower embossing-cylinder, and this spur-gear meshes in turn with a similar mounted in substantially the same manner as the corresponding upper and lower printingcylinders hereinbefore described, the upper embossing-cylinder E being removable from and adjustable in its bearings in the same manner as the cylinders C and C'. The workingsurface of the embossing-cylinder E, however, is made up of a circuit of male dies, such as those indicated herein in detail in Fig. 13 by S5, these dies being of such shape and so positioned as to emboss the traveling web w in the proper manner, this web usually being embossed between the printed portions thereof. The lower embossing-cylinder e need not have female dies, however, to coperate with the male dies but instead the working surfaces thereof may be a yielding one of any suitable material for this purpose, although I prefer to wind around the cylinder e a plurality of layers of tissue-paper, such as S6, which being quite yielding will permit the male dies 85 to sink into them, as indicated at 86', and thus form a female die during the moment that the web is being embossed. There is an important advantage in the use of such a yielding covering as this, as tissue-paper after being indented in this manner will return almost immediately to its normal position and will not remain permanently indented.

Any suitable inking mechanism may be employed for applying a suitable printing medium or ink to the printing-cylinders; but I prefer to employ the improved inking apparatus herein shown in connection with the cylinders C and C. As before stated, they are substantially identical in construction, and a description of one will also suffice for both, this construction forming the subjectmatter of another application for Letters Patent, Serial No. 729,798, filed September 8, 1899.

The inking apparatus embodies two essential elements, one of which is the ink-fountain and its cooperating parts and the other ink-rollers and devices coperative with the printing-cylinder, to which rollers the ink is.

transferred from the fountain. The inkfountain may be of any suitable construction; but I will usually employ a fountain, such as that designated in a general way by F, capable of reeiprocation endwise on a support or cross-bar 90, connecting the two side frames IOO IIO

A A. The connection between the fountain and the cross-beam 90 may be made in any suitable way; but I prefer to mount said fountain on a dovetailed guide, such as 91, bolted. to the cross-beam in such a manner as to be removable therefrom toward ,the righthand side, as seen in Fig. 4. On this dovetailed guide 91 the fountain may reciprocate endwise, it having in this case a cooperating dovetailed guideway 92 in its under side. This ink-fountain supports therein the usual ductor-roll 93, and a transfer-M1104 is journaledA in the ends of a` pair of links 95 and 96, pivoted to opposite sides of the fountain. This transferroll will make contact alternately with the ductor-roll and with another roller of the inking.r apparatus to transfer ink to thelaiter. The ductor-roll should ofcourse turn to lead the ink to the transfer-roll 94, and an intermittent step-by-step rotary movement may be imparted thereto in any suitable manner, as by means of a suitable Vpawl-andratchet connection, (indicated ina general way by 19,) the ratchet-wheel being secured to a short shaft 07, journaled in a suitable bearing and having at its opposite end a squared longitudinal bore, such as 97, in which a correspondingly-squared end 90' of the ductor-roll shaft 98 may slide as the inkfountain reciprocates. The link 100, by which motion is communicated to the pawl-and- `ratchet connection 19, maybe connected bya suitable spring-pressed rod, such as 101, to the shaft 12 and suitably operated by a cam or wiper thereon, the spring serving to return the parts to their normal positions to indicate the feed.

The reciprocatory movement of the inkfountain may be obtained in any suitable manner; but in this instance a large spurgear 102 on the shaft S (see Figs. 3, 4, 5, and 0) has on one side thereof a circuit of projections and depressions forming a crown-cam, (designated herein by 103,) with which coperates an antifriction-roll on the end of a lever 104, carried by a shaft 105, suitably journaled in the framework. At its upper end this lever 104 may be connected by a link, such as 105', directly to the ink-fountain to shift the same in one direction, a suitable spring, such as 100, being employed to effect the return movement of said fountain. Another lever-arm, such as that shown at 107 and formed substantially as a shipping-lever, may be secured to the shaft 105 and may serve to impart a reciprocatory movement to one of the inking-rollers which coperates with the printingcylinder.

In order to permit access to the cylinder C, especially in removing the latter, I prefer to employ an inkin g device shit'table toward and away from said cylinder, and the main inking device, which is indicated in a general way by I, may be supported for oscillation on the bearings of the shaft 52. This main inking device will usually embody a pair of side frames or rock-arms, such as 110, which may be connected by a rod 112, and the main inking-frame may be secured in its working position by a latch and a detent, such as 113 and 114.

Any desired number of inking-rollers may be supportedon the rock-arms 110, and they may be mounted in any desired manner; but I prefer to support thereon two shafts, such as 115 and 110, carrying inking-rollers 117` and 118, these shafts being geared directly to the spur-gear 102 by pinions 119 `and 120. The shafts 115 and 116 are not in this case, however, journaled directly inthe rock-arms 110, but are preferably carried at their opposite ends by yielding bearings, all of which are of the same construction. By referring to Figs. 3 and 4 it will be seen that these shafts are journaled directly in spring-pressed bearings, such as 125, suitably guided in the rock-arms 110, and that the bearings in the latter are open at their upper sides in order to permit the shafts to be removed readily with their yielding bearings. A third frictionally-driven ink-roller, such as 130, in contact with the ink-rollers 117 and 118, is carried by a shaft 131 in transversely-elongated bearings in the rock-arms 110.

In addition to the parts just described the main inking device will preferably carry a second inking device supported thereon for 1 oscillation relatively thereto, and in this case the shaft 116 may form the support for the second inking device, this latter having oscillatory side plates or links, such as 135, connected, as by the shafts of the inking-rollers, to form a suitable frame, said side plates or links having proper bearings for ink-ro1ler shafts. I-Iere two of these shafts are journaled directly in such side plates, said shafts being designated by 136 and 137 and carrying corresponding ink-rollers 138 .and 139. The shaft 136 may be supported for reciprocation in its bearings and may be reciprocated by the lever 107, hereinbefore mentioned. (See Fig. 4.) Moreover, the bearings for this shaft may also be transversely elongated, as are those of the shaft 131. The ink-roller 13S is frictionally driven by contact with the ink-rollers 118 and 130, the latter of which oscillates with the second inking device t' toward and from the surface of the printing-cylinder. When in its working position, this inking-roller 139 constitutes a second transfer-roll, and is intended to oscillate between the first transfer-roll 94 and the surface of the cylinder, it serving, as shown in Figs. 7 and 8, to raise the gravitative transfer-roll 94 from the ductor-roll and take a portion of the ink and to permit the roll 94 to come into contact with a newly-inked portion of the surface of the ductor-roll when the roll 139 descends to ink the printing-surface.

The oscillatory movements of the device i may be obtained in any suitable manner--as, for example, from a rod 140, engaging, but not connected to, some suitable portion of IOO IIO

ITO

a earn on the latter, the weight of lthe inking device serving to impart the return stroke to the rod 140.

In order to limit the movement of the inking device t' relatively to the main device I, the latter may have thereon a fixed stop 145 in position to engage some suitable member of the device t' when the main and second inking devices are thrown back to the position shown in dotted lines in Fig. 3.

The bottom plate or ductor of the ink-fountain, which plate is indicated herein by 150, may be adjusted at its feed end relativelyv to the ductor-roll by suitable adjusting-screws, such as 151, in order to control the thickness of the ink-film led off by the ductor-roll.

' The second inking apparatus, which coperates with the second printing-cylinder, is substantially similar to that just described, the main and second inking devices being indicated in a general Way by I' and i', respectively. Here the rotary movements of the inking-rollers are obtained from the spurgear 53', and the actuating connecting-rods 101' and 140' are operated from the shaft 15.

The manner in which the guide-rollers controlling the registering of proper portions of the web with corresponding patterns or devices of the printing or embossing cylinders are adjusted is clearly shown in Figs. 3 and 4,

from which it will be seen that the shaft 155 y of the roll 40 is carried at its ends in vertically-adjustable bearings working in vertical guitleways in the side frames, these bearings preferably having square-headed bolts 156, working in corresponding T-guides in said frames, nuts 157 being employed to clamp the bearings in their adjusted positions.

As it is desirable to dry the ink or printing` medium on the web before the latter reaches the embossing-cylinders, I prefer to employ a drying device located between the second set of printing-cylinders and the embossingcylinders. Any means suitable for the purpose may be employed; but I have shown herein a hollow cylinder 160, overwhich the Vweb passes and bywhich it maybe supported, it being noticed that the heatis applied from the lower or unprinted side of the web. This heating-roll may be supported on a hollow perforated rod or pipe, such as 161, communicating with a `gas-pipe, such as 162, leading from a proper source of supply and having ayalve 163 therein for controlling the flow of gas. Said roll may have secured thereto a pinion 164, meshing with the gear 17' and driven thereby. The gas issuing through the perforations in the pipe 161 will be lighted at the proper time, aud the heating-roll 160 will be uniformly heated owing to the rotation thereof.

Any proper means may be employed for separating the web from the heating device when the machine is not running, as the web would be liable to be scorched or burned if it Were not separated from the roll at such time. Here, however, I have shown at 170 a web-raising lever having an antifriction-roll engaging the under side of the web tu adjacent to the heating-cylinder 160, this lever being joined by a connecting-rod 171 to a rockarm 172, carried at one end of a side shaft 173, to which a start-ing and stopping lever 174 is secured in order that the web may be raised from or lowered onto the heating-cylinder si- -multaneously with the stopping or starting of the machine. To theshaft 173 may be secured the usual shipping-lever 180 for shipping the driving-belt 9 onto the fast or the loose pulley carried in the usual way by the driving-shaft 10 of the machine.

Some of the ink from the printed surface of the web usually adheres to the upper enibossing-cylinder E as the web passes between the embossing-cylinders, and for the purpose of removing the ink from such cylinder' I prefer to first heat the latter and afterward clean olf the dried ink by brushes. I-Ience I have illustrated herein at 190 a gas-pipe having therein a suitable valve 191, connected to a heating device (indicated in a general way by 7L) around which one or more shields or heat-deflectors, such as 193 and 194, may pass to direct the heat of thevflame upward and against the surface of the cylinder E to thoroughly dry any ink adhering thereto. For cleaning olf this ink I may employ one or more rotary brushes, and in this case I have shown two brushes 200 and 206', disposed at opposite sides of the cylinder E and carried by shafts journaled at their ends in rockframes 205 and 205', suitably pivoted on the framework and of any proper construction. These brushes 200 and 200' may be driven by belts 206 and 206', passed around pulleys 207, 208, 207', and208", the pulleys 207 and 207' being connected in this case by another belt 209, and the pulley 207 being connected by a belt 210 to another pulley 1b", carried by the shaft 16. It will be noticed that these brushes are connected by belts in such a manner as to 'permit the rock-frames to be swung back and forth, as it is necessary that the brushes be shiftable toward and away from the cylinder E in order to permit the removal of the latter. Y For shifting said brushes I may make use of knuckle-joints, such as 215 and 215', which may be operated by cranks or levers 216 and 216'.

The operation of my improved machine will be fully understood from the foregoing description, but may be briey stated as follows: The gas may be first lighted in the two heating devices, and after the web or paper has been properly started the adjusting takeup rollers 40 and 40', controlling the impression, will be properlypositioned and clamped, the proper operation of the parts being tested in the usual manner by drawing the paper through the machine and also by testing for impression and registration of the impres- IOC IIO

sions. If everything is working properly, the lever 174 will be shifted to start the machine and the web will be fed forward, a suitable pressure being exerted by the retarding device T and by the tension device T' to maintain the web taut between the winding and rewinding rollers` Theweb will `first pass between the cylinders C and c, and the former being properly inked will print the upper surface of the web usually in one color, after which the web will pass onto the second setof printing-cylinders and a registering impression will be made on the upper surface of the web by the properly-inked cylinder C. The web will then pass to the webdrying device or cylinder 1GO, and the moist ink will l be properly dried thereby, after which the web passing between the embossing-cylinders E and e will be embossed between the printed portions thereof and then rewound on the roller r', by which the web is drawn through the machine and which will regulate the rewinding of the web into a roll R with su'fcien t, but not undue, tension. Ink adhering to the cylinder E will then be dried and brushed off from successive portions of the surface thereof before said portions are again brought into contact with succeeding portions of the web.
